[0024] The technical solutions and technical effects of the present application will be described in detail below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all. EMBODIMENT

[0025] As Figure 1 , Figure 3 and Figure 4 , an embodiment of a gas stove air curtain device includes a housing 1, the housing 1 has an oval ring or square ring cavity surrounded by a top plate, a bottom plate, an inner side plate and an outer side plate, and the present embodiment is a long rectangular ring cavity. The cavity is fixedly installed with an air pipe 4 which is consistent with the cavity and in the form of a hose.

[0026] Specifically, in combination with Figure 4 , Figure 5 and Figure 6 , the air pipe 4 is sleeved with a clamp 5 for clamping the air pipe 4, and the lower end of the clamp 5 is fixedly connected with a clamping head 5-1. Correspondingly, the outer side plate is fixedly provided with a clamping block 1-2 which is horizontally oriented and located below the air pipe 4. The clamping block 1-2 and the clamping head 5-1 are connected with each other to fix the air pipe 4 in the cavity and make the upper side of the air pipe 4 adhere to the lower side of the top plate.

[0027] As Figure 7 , a plurality of air outlets 4-1 are formed on the upper side of the air pipe 4. Correspondingly, the top plate is provided with air outlets 1-1 corresponding to the positions of the air outlets 4-1. The high-pressure gas in the air pipe 4 is sequentially injected upward through the air outlets 4-1 and the air outlets 1-1 to form an air curtain for enclosing the oil fume, which restricts the oil fume within the effective suction range of the range hood to prevent diffusion.

[0028] Specifically, the longitudinal section of the air outlet 1-1 is V-shaped. The air outlet 1-1 is provided with a rubber nozzle 4-2 which cooperates with the air outlet 1-1 and sprays air flow upward, the rubber nozzle 4-2 is embedded in the air outlet 4-1 through the ball head at the bottom of the rubber nozzle 4-2, and the ball head is provided with a vent hole for guiding the high-pressure gas in the air pipe 4 into the rubber nozzle 4-2.

[0029] As Figure 4 and Figure 5The shell 1 is fixedly connected with a mounting rack 1-3, and a drawer 2 is slidingly installed on the mounting rack 1-3. A power supply module is arranged in the drawer 2, and the power supply module is generally a power storage device such as a power bank, and the power bank is provided with an input interface and an output interface. Generally, the panel of the drawer 2 is fixed to the shell 1 by screws.

[0030] Optionally, in order to facilitate replacement of the power storage device, a lock catch with a press locking / unlocking function can be arranged between the drawer 2 and the shell 1.

[0031] The utility model also includes a pump air device 3 for supplying high-pressure air to the air pipe 4. Figure 3 In the embodiment, the pump air device 3 includes a fan 6 installed in the shell 1. The air outlet of the fan 6 is connected to the air pipe 4, and the air inlet is connected to a section of air inlet pipe which extends out of the shell 1 and is away from the shell 1 by a certain distance to avoid interference of the air inlet flow with the air pressure environment of the gas stove burner.

[0032] The fan 6 and the power supply module are connected with a control switch 7 which is installed on the front side of the shell 1. Embodiment

[0033] As Figure 8 The difference between the embodiment and embodiment 1 is that the fan 6 of the pump air device 3 is arranged outside the shell 1, and the air outlet end of the fan 6 is communicated with the air pipe 4 during use.

[0034] Preferably, the power supply module and the control switch 7 are integrated in the pump air device 3, and the pump air device 3 can be directly operated during use.

[0035] During implementation, a common portable inflation device for inflating swimming rings, inflatable mattresses and the like can be used as the pump air device 3 in the embodiment. Such products are generally provided with lithium batteries and can be charged through a USB interface, and are more convenient to use and maintain.

[0036] The scheme of embodiment 1 is more suitable for home kitchens, and the scheme of embodiment 2 is more suitable for restaurant fields.

[0037] As Figure 2 During use, the utility model is placed on the side of the gas stove, and directly below the exhaust hood. Under the combined action of the air curtain shielding and the suction force of the exhaust hood, the oil fume generated by the gas stove is sucked away by the exhaust hood to avoid horizontal diffusion of the oil fume.

[0038] It should be noted that, for those skilled in the art, it is obvious that the utility model is not limited to the details of the above-mentioned exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. The scope of the utility model is defined by the claims rather than the above description.
